Não perca o seu drone!!! Dicas valiosas de DJI Phantom 3 e 4 #5 (EN-US/PT-BR)
Hi, guys! All right? Welcome to the Konter channel. Today, let's talk about fly away, which was a theme suggested by
our friend Adriano Pimentel, which is a much discussed
topic among drone pilots or those interested in the subject. Let's go! After all: What is "fly away"? "Fly away" is a generic term; it occurs
when you lose control of the drone, it creates its own life, it flies away,
and you no longer have control of it. You totally lose control of the drone.
It creates its own life and goes
flying around, until it falls, or hit something, that will fall, too. That is: the battert will end…
you lost the drone. And what makes that happen? A lot of people won't
like me to say that, but usually it's because of
the pilot's mistake. But, this can also be caused by
interference, by external factors, and even by manufacturer error. I'm going to give ten tips of
things that can be done to avoid both the fly away and other things
that, in fact, are not fly away.
So, I'm going to list 10 items here, and you guys feel free to comment on them. Adriano, who suggested the video, asked me: Is it normal to fly away? Whit which
drone models occur more fly away? He even cited that he
is buying a drone, and he asked me if he
is taking that risk. And I told him:
We are not free to fly away; But, it's one thing that does not
happen much whit the current drones because the technology that
is used is GPS and Glonass; then the location point, the centralization of the drone's
location is very accurate. But of course, if you have an
interference, if you have a human error, it can cause the fly away,
we can lose the drone; then we are not free from it. Remembering: human error will cause it. Let's get the 10 tips for you to avoid
losing the drone, or a fly away. The first tip is this: every time
you go flying with the drone, do the drone calibration,
the compass calibration, because if you don't calibrate the
compass, you can't set the Home Point; and, if you need to give a Return To
Home, that is, bring it back to you, the drone won't know where he left; so, sometimes, you visually lose the
drone, then and you push the button, it will get lost, and it goes away;
you won't be able to get it back.
So, always before flying, it is
not just to press the buttom, to turn on the battery, to start the
engine and to flight. Do the calibration. Follow the pre-flight steps, otherwise you
run a serious risk of losing your drone. If I'm not mistaken, six
satellites are necessary for you to set your Home Point. Then, turn on the control battery, turn
on the drone battery, let it warm up, and, in the meantime, it will
start looking for satellites. When it find six satellites, you
already set the Home Point; it even gives you a Home Point warning or, if not, it has an on-screen icon
where you can select the Home Point.
So, always do that. Item 2 is about a somewhat
controversial maneuver, about what people say, "Oh,
DJI should disable it," or, "Oh, I didn't do it";
but in fact, the pilot did, which is the CSC command. The Combination Stick Command (CSC) occurs
when you take control of the drone and you put the sticks
in a certain position; then this causes the drone
to turn off automatically; it simply shuts down the motors. I'm going to show you this
command here, in the control. The CSC occurs when you position
the sticks in this direction, or to the middle. In this situation, you turn
off the drone's motors. The CSC automatically shuts down the
drone, causing it to fall where it is.
So, sometimes you're doing some
maneuver, wanting to get down a little, running around an object, a scene, But you end up putting the
sticks in the positions that I showed; you unintentionally
turn off the motor. So, you have to be very careful
when doing this maneuver. There are many people who ask: "If I hold the stick down for 3 seconds,
will I turn off the motor, too?" While the drone is in the
air, you don't turn it off.
This command to turn off the
drone's motors only works when it isn't flying, and you
hold the sticks for 3 seconds. this way, the motor is turned off. So, there's no risk of you turning off the
drone, making it go down while it's flying. The third point is this: there are people
who in a hurry to want to film a scene, to want to fly, do not attach
the propellers correctly. There's a right way to
attach the propellers.
Remembering that the
drone has 4 propellers: two are in silver, two in black. So, you take the black propeller
and you put it on the black tip. The drone has the signal here indicating which side you should spin the propeller; And in the propeller, too, there
is the side you have to lock it. I'll put it here, horizontally. It's
showing that, in order to lock, I need to rotate it counter-clockwise. So, I give it a trot. When you realize that it
takes a turn, or it stops, it gives a little trot; it means
that the propeller is locked. If you don't attach the
propeller correctly, the propeller may
release during flight, causing the drone to destabilize,
and it will fall; it has no way.
The drone won't be able to sustain
itself with 3 propellers. So, be very careful when
attaching the 4 propellers. Take your time; do it right. On the fourth point, we'll talk
about a theme which is a challenge for drone pilots, which is
to want to go further, to want to get an image
that is up there, or to prove that the drone manages to
reach 5 km, which is what DJI affirms. The pilot says: "I want
to get to 5 km away". The drone goes flying; it goes
away; the drone is getting there; 2.5 km; 3 km…
But the
battery is consuming; you reached 5 km with 50% battery. Then, you think: "Cool, I can go back because I've spent 50% to go, I'm
going to spend 50% to go back." However, if you don't have enough battery to face a gust of wind, a wind a little
bit stronger, the drone will fall. "Well, but the drone can stand
winds of up to 50 km/h." How does the drone stand it? It needs to run the motors
faster; it spends more energy, it needs to consume more energy to
ensure speed and to fight the wind; so, the 50% won't be 50%,
it will be 40%, 30%; bear in mind that, with 10% the
drone makes the emergency landing. Then, you don't have 50% to go
back, you have at least 40%. If you catch a wind, get some obstacle that you need to divert,
where is the battery? You won't have it; the drone
will fall along the way.
Then, you will say, "Well! I lost its
control, it got lost and it fell." It wasn't quite like that;
it was your miscalculation. So, be very careful when thinking:
"Oh, I'm going to film very far." Your battery may not be in
the best of conditions; so you have to be careful;
guarantee a safe flight. You have 30% of battery,
back soon, avoid problem; take a new battery; I know it's expensive,
but try to have at least 2 batteries to make a safe flight.
Whenever you follow the steps for safe
flight, you won't have problems. Let's go to the fifth tip: On the fifth tip, we'll talk
about flying over water. I already have a video about it; you can watch this video here; I'll put the card up
here for you to access. Here is the deal: When you fly over the water,
or over some outdoor objects, I recommend that you turn off the VPS because the drone can be confused
with some things, like brightness, the reflection of the water, causing
the drone to get lost and fall. When you are flying over a lake, or some object that may appear underneath
the drone, it may want to deviate; it'll get confused there, it'll get lost,
it'll say: "Where am I?" and it'll fall. So, be very careful. Sometimes, people say: "Oh, I lost
my drone flying over a lake" or "over a building".
And,
sometimes the reason is this: due to some reflection or
brightness, it is lost and falls. Then, turn off the VPS. The sixth tip refers to
the speed of the drone. Sometimes, people thinks: "Oh, I'm
going to make a quick filming toward a certain object, and when
I get too close, I'll stop". Just like a car, the drone
also needs a space to brake; the drone is going fast, so
if you put the stick back to brake, it won't do a turnabout
manoeuvre like a drifting; It'll slow down, and then
it'll start to reverse.
The drone needs to stop the departure
so it can starts the return; and, to stop the going, it
requires a few meters, too. Be careful; If you are flying fast
in the direction of something, take it easy; you'll need a plenty of
space, otherwise your drone will hit. Then you lose the drone, and
you'll say, "Oh, it came to life, it kept flighting, I gave it
the command to come back." No. You gave it the command to
come back too late. Be careful. In the seventh tip…
This seventh
tip is also considered as a fly away because the drone may suddenly fall.
Why does it suddenly fall? Maybe you are flying without keeping
the drone in your visual field. So, it's there at 200m hight,
you don't see the drone; when the drone is at 100m high
you maybe no longer see it; if it is a sunny day or a day with white
clouds it'll be difficult to see it.
And its leds blink, but that
doesn't make much difference. So, you're flying there,
let's suppose: 150m, 200m; at a distance of about 100m ahead of
you; you don't see the drone anymore. What is your vision? Your vision will be the image of the
drone camera projected on your mobile. You are seeing the drone camera; so what are you seeing forward
to, back to, up to, or down to? Forward, just its camera image; to
the other sides you see nothing. If you want to continue filming forward, and you walk a little to the side,
but if it has a high voltage cable, if it has a line, if it has a
line of kite, for example, your drone will screw there and fall.
"Well, but if the propeller hits the
kite line it will cut the kite line." Yeah. What if it doesn't hit the propeller? If it catches the drone's
body, if it twines the drone in some way,
the drone will fall; it'll get lost and fall; in a high voltage cable,
it'll be the same thing; on a branch, it'll be the same thing; so, you need to be careful
about your visual field. If you can't see it, there may have a
bird, or several birds around the drone; they'll hit it, and it'll fall. So, be careful when you go flying
and you don't have visual contact. That's why, in many
countries, it is forbidden to fly without visual contact; you have to fly in the open,
always seeing your drone. In the eighth tip, this
tip is a basic thing, but, come on; it's always good to
comment, always good to emphasize.
Sometimes, people want to fly
over substations of electricity; they want to fly to inspect some antennas;
they want to fly over buildings; they want to fly on Paulista
Ave to enjoy its view; but they are places that have extreme
electromagnetic interference; Wi-Fi signals; radio signals; and these things get in
the way of communication with the drone; all
are radio frequency. So, several radio frequency emissions,
in the same place, will give problem. Sometimes, when you are driving
on Paulista Ave, in your car, the radio broadcasting
station that you listen all over São Paulo, at Paulista
Ave it doesn't work. Why doesn't it work? Because there are many
signals emitted there. So this interference
also affects the drone. I know several reports of people who
lost the drone at Paulista Ave because there are lots of antennas
and radio frequency signal there; so be careful; avoid flying
in this type of place; the probability of you
losing your drone, of it flying out, which is the
real fly away, i.e.: the drone goes away and
it no longer responds to your commands, the
probability is giant.
So, be very careful; avoid
this kind of place. In the ninth tip, we're
going to talk about something that saves a
lot of people's lives, it saved my life about 3x on the last
trip I did, which is Return to Home. In this configuration, there's
a default preset in which, the moment you press Return to Home,
the drone rises 30m from where it is; so, the drone is here, it goes up 30m
and it comes back to where it left, in case you have set the Home Point. I'll bring it to my situation. I was flying with the drone; at one point, the drone
was near a mountain, I couldn't see where it was; I turned the camera to try to
locate it; I saw nothing; I saw no place close to me; I
pressed the Return to Home button; it climbed 30m and it came back.
Phew! Did it work this time? Nice. But, in another time, I
missed the drone signal. I was there piloting the drone quietly
near a castle, I was filming a castle; Only it appeared on the screen:
"Aircraft disconnected". At that time, I froze with fear;
I said: "I lost the drone". And the drone was on the
other side of the castle. I was in this position, the castle here
in the middle, and the drone was after. I'm going to post a video
showing this scene. But, what happened? Is showed
"aircraft disconnected"; only I was a little below
on the other side; I had passed by the castle and
I was a few meters below, which would be the limit of those 30m. So, what happened? When "disconnected aircraft" appeared on
the screen, the drone began to return; It gave Return to Home alone,
because it lost the signal; it climbed up and it
came toward the control, toward the Home Point, toward me. Only it went up and it almost hit the
castle tower because I was lower; it climbed up to 30m, and those
30m were practically the limit of it goes through the castle tower; it almost hit the tower.
This was not a reckless flight situation. I was filming and, all of a sudden, I
lost the connection by interference; it went up 30m; It was just
enough to pass the tower. Maybe, I should have set up
more meters for it to rise, to rise to a greater height; it could barely get through. By the time I regained control of the
drone, when its signal returned, it was coming too close the tower; I still gave a little touch
on the stick, and it passed; then I got the drone back. So if you do not set it up properly, or if you leave this setting
at 0, what is possible; if you disable it, you run the
risk of losing the drone, too; besides, you have to be careful
because, sometimes, you are flying in a place that you
don't have the visual contact; you give the Return To Home, and it'll go
up 30m, for example, which is the default; only when it goes up, there's a
tree, there's a roof over there, you're flying underneath something,
there's a bridge, whatnot; then, it's going to hit something
and it won't come back to you.
Then you say, "OMG! I lost
control of the drone." In fact, it hit somewhere; Then it's a human error; you're
flying without a field of vision. In Tip 10, it's actually advice because, sometimes, people start
getting excited about some images, with some takes, and they start wanting
to film some things from other angles. There's the case of you seeing
an animal, seeing an object, and you want to make the Point of Interest, which is to rotate by that
object, filming it from above; if you don't calculate that radius
right, maybe in that diameter you're going through there's a tree, there's
something that you're going to hit; so, watch before filming some scenes
because there may be some obstacle there.
That's no good you just look
at the drone's camera. You shouldn't have this
FPV, first-person view; you have to look sideways, too;
you must have a field of vision. I'm not much in favor of those FPV glasses, unless you are with somebody
on your side who's helping you because you have no vision
of the field around you; you don't have the vision of
the drone, just its camera. So be careful when making these takes. The 10 tips have already been given.
I'm going to get an extra tip now, which is for those who just
got the drone, and they say: "Ooh! Cool! This drone is
good for flying indoor; I'm going to film a wedding, I'm
going to film a birthday party." Hey! Wait! You just bought a drone; you
have no experience with it; will you want to fly inside
a house, inside a church? What if it falls? What if it hits
somewhere? What are you going to do? And if it hits or it falls on someone else? So every time you try to do an indoor
flight, you have to keep in mind that: an indoor flight has no satellite signal, you won't be able to get a
signal from Glonass or GPS; so it will not get stabilized. The first step is: go to an open field and fly in Mode A, which is in manual mode.
Train in this mode, the ATTI
mode; then, train hard; you'll be able to maneuver the drone in
a different way than with GPS signal. Then go to a place, a
shed that is wide open; train in there; you won't
get wind interference; you'll know which way to
turn on; so train there. Then, put the propeller guard and
go to a more enclosed space, and get used to filming
in these environments, until you think of something
more professional, like filming narrow places,
weddings, parties; always being very careful
not to fly over people, near people, because propellers
hurt, cut, dilacerate people. So be careful, be sensible
with what you're going to do. And, now, the extra-extra tip, to say we're
finishing the video, closed, enough. Every time you fly with the drone forward, when you put the right stick
forward, the drone goes forward; when you put it to the left,
it goes to the left; right, right;
backward, backward.
If you rotate the drone, and the camera
turns to you, the commands reverse! So, be careful. You put it to the right,
it goes to the left; so be careful, ok? There's a function that disables it; so, whenever you put it
forward, it goes forward; to the right, right; to the left, left;
to the back, back. But, if you don't know how to do it now, I'm going to show you how it's
done in other video, be careful; you've reversed the camera, if you put
it to the right it goes to the left. A lot of people lose the drone
because, they think it's coming back to them, but they're
taking the drone farther away; it'll lose the signal; the battery will
run out and the drone will go away. Then, the person says: "Well, I had
a fly away". In fact, you did it. You took the drone away, thinking
you were bringing it close; the battery ran out and it fell;
you lost by your mistake.
Maybe this person says: "Oh, DJI makes a product that
has no quality whatsoever, that goes down anyhow, that goes
away, that has life of its own." It will be? It's not your fault, is it?
It could be. So be careful before blaming it
because the equipment is good. Are there failures? There are. But, much failure is human. I already made mistakes, I still haven't
lost a drone and I don't want to lose it; but most of the problems
are due to human error. We are talking in this
case about a Phantom 3; they've produced Phantom 1, Phantom 2; the Phantom 3 has 3
series; they've produced Phantom 4, and they've
launched the Mavic; so they know what they're doing; and the reports of drone falls
by fly away are very few in comparison to the quantity of products that they sell; then, is it really that
their product is not good? But, that's it, people.
